exam 2 (L2) - gingivectomy and gingivoplasty Flashcards
1
Q
what is the definition of a gingivectomy surgery?
A
excision of soft tissue wall of a perio pocket
2
Q
what are the 3 indications for gingivectomy?
A
- eliminate gingival enlargement (hyperplastic tissue)
- eliminate suprabony pockets
- eliminate suprabony perio abscesses
3
Q
3 contraindications for gingivectomy?
A
- pockets extending beyond mucogingival junction (MGJ) / minimal attached gingiva
- pockets with significant furcation involvement
- osseous defects where flap surgery is preferable
4
Q
3 different general approaches to gingivectomy?
A
- EXCISE tissue via surgical gingivectomy w/ external beveled (scalloped) incision
- VAPORIZE tissue via electrosurgery
- VAPORIZE tissue via laser gingivectomy
5
Q
what is the technique for a surgical gingivectomy?
A
- under anesthesia, mark pocket depths (stab)
- external beveled (scalloped) incision (Solt/Kirkland)
- interproximal incision (buck, orban knife, #12B scalpel)
- tissue removal + root planing
- gingivoplasty (perio knife/scalpel/diamond bur)
- perio dressing
6
Q
define gingivoplasty
A
reshaping the gingiva to create physiologic gingival contours. NOT done when perio pockets present
7
Q
why is gingivoplasty performed?
A
to remove thick gingiva
8
Q
is healing after gingivectomy done through primary, secondary, or tertiary intention?
A
secondary
9
Q
what does the gingivectomy healing process involve?
A
secondary intention:
- clot forms
- clot replaced by granulation tissue
- surface epi forms (5-14 days)
- complete epi repair (4 wks)
- complete CT repair (7 wks)
